Frequency Polygons Are Used For – Applications
Here are some of the key applications of frequency polygons:
- Comparing Distributions: Frequency polygons allow for easy comparison between different datasets. By overlaying multiple polygons on the same graph, you can visually assess differences in shapes, spreads, and central tendencies of the distributions.
- Identifying Skewness and Kurtosis: The shape of a frequency polygon can provide insights into the skewness (asymmetry) and kurtosis (peakedness) of the data distribution. This is useful for understanding the nature of the dataset, whether it is normally distributed, positively skewed, negatively skewed, etc.
- Analyzing Trends: In time series data, frequency polygons can help in visualizing trends over time. This makes it easier to identify patterns such as seasonal variations or cyclic changes.
- Educational Tool: In teaching statistics, frequency polygons serve as a clearer alternative to histograms for some students. They can help in understanding how frequencies change between intervals.
- Cumulative Frequency Analysis: Although not a cumulative frequency graph itself, frequency polygons can be adapted to show cumulative frequencies, providing a visual representation of data accumulation over intervals.

Frequency Polygons in Statistics
Frequency Polygons in Statistics: A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions. It uses a line graph to represent quantitative data.
Frequency polygons are one of the great methods to represent statistical data so that it can be read easily. In statistics, we deal with lots of data, and reading it quickly is necessary for solving statistical problems effectively.
Frequency polygons help us to achieve the same result. In this article, we will learn about frequency polygons, their formula, examples, and others in detail.
